Audio and podcasting decision
Speechify
A competent developer can build a useful web TTS replacement (upload, play, download, basic voices) in about a week, but Speechify's scale, large proprietary/celebrity voice catalog, native apps, and brand reach are not easily reproduced—so building a narrower DIY alternative is sensible, while keeping the paid product for full-featured voice catalogs and cross-platform polish.

Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All Speechify alternatives, with the arithmetic →
What a replacement has to do
- Upload or paste text → select voice & language → synthesize audio → play and download audio (optionally save document).
What it still won’t have
- Large catalog of 1000+ proprietary/celebrity voices and custom studio voices
- Cross-platform native apps (iOS, Android, macOS, Windows) and browser extensions
- Advanced voice-cloning, dubbing, studio captions, and enterprise features
- AI assistant conversational QA across user documents and advanced meeting agents

The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a minimal Speechify-like web app using React for the frontend, Node.js + Express for the backend, and Postgres for user/document storage. In scope: paste/upload text (PDF/DOCX/TXT/EPUB), extract text server-side, present voice/language selector, call a third-party TTS API (configurable via env var) to produce MP3/OGG, stream playback in-browser, allow audio download, and save documents and user preferences. Out of scope: mobile native apps, celebrity/custom voice licensing, voice cloning, enterprise SSO/billing. Include robust error handling, request retries, per-user rate limits, simple JWT auth, Dockerized deployment, CI tests (unit for parsing & TTS integration, end-to-end for upload→playback), and an infra cost estimate for production (small VPS or managed service).

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
